Sorry to hear that. I have no idea about Australian health care, but are you sure your primary care doctor can't prescribe those meds for you? They might be more willing to prescribe the non-stimulant meds. It's worth asking them if you aren't 100% sure they won't.
Also, i definitely strongly suggest researching psilocybin mushrooms. Of course do some research first and see if there are any reasons for you personally not to do them. But yeah, they make a huge improvement in many people's lives
